Should Tesla Charge to 80% or 90%?
2 Answers
Tesla can be charged to either 80% or 90%. Charging the battery to 90%, or even 95% is fine, and even 100% is acceptable, but it is not recommended to charge to 100% because energy recovery and the braking system do not function effectively at full charge, resulting in lower energy efficiency for the vehicle. Below is the relevant information: Introduction to energy recovery: This refers to the process where, when the driver releases the accelerator pedal, the vehicle controller determines whether to engage braking energy recovery at a given moment based on the brake pedal's opening, the vehicle's driving state information, and the power battery's status. For example, when the power battery's temperature is too low, energy recovery cannot be performed, and the amount of braking energy recovery is determined based on the remaining charge of the power battery. Optimal charging: Charging within the 25% to 80% range of the battery capacity can reduce battery capacity loss and extend its lifespan while ensuring sufficient power availability.
I've been driving an electric vehicle and found that charging habits are crucial for battery health. For Tesla's lithium-ion batteries in daily use, consistently charging to 100% accelerates aging. It's recommended to set the charging limit to 80%, as the battery experiences significantly less stress at this level, potentially extending its lifespan by several years. Occasionally charging to 90% is fine, especially when extra range is needed for weekend road trips, but avoid doing it frequently to prevent accelerated battery degradation. For daily commutes, 80% is perfectly sufficient and can even save on electricity costs. I easily set the charging limit on the mobile app, and after getting used to it, I find it quite hassle-free. Additionally, avoid fast charging on hot days and combine software updates to optimize charging times for a smoother overall driving experience.
